But that's a good idea about using 1/8th tires
Come to think of it, do they still make 1/8 donuts?

And if so are the rears wide enough to make two 30mm touring tires?

I think with one 1/8th rear tire you could make 3 tc rear tires. With 1/10th rear you can make 2 rear tires

With the rears you can make two 30mm or three 26mm if you are real care full, fronts you can only get one of either.

Most likely from the mainland. Nobody here got any. Hobbietat has some old 235 donuts, also Ace. But they smell heavy of cigarette smoke. Have fun mounting tires, contact cement and laquer thinner. Ask Joe if he still has a tire horn.

BTW, are you able to get unmounted wheels to mount your own tires??

i wouldn't mind giving foam wheel building a shot -- especially if we follow through with the tire lathe

Well, you can get lexan rims without the rim bead from OFNA, but I would suggest grinding off the part of the rim where the tire bead sits in before going with OFNA rims... . Other companies must make rims for foam tires (without the tires themselves, but I don't know that).

i try to stay away from lexan wheels -- it's got that mean cracking issue.....for some reason, the more you stay away from the boards, the more your wheels become a magnet for others to colide into -- enter the CRACKING ISSUE!

Arrow the right size

how are you guys finding the "right size" for your foams?
Some say their car runs best at a certain size fronts/rears.
Do you just run the car and dirve it until it "feels good" and then measure the front and rear tire diameters? Or, do you go and true tire to different sizes then test?

Both.
For me its by driving. But I forget to measure the tires.

Definitely run better when they get small. I've seen some guys toss foams away before I think they are even small enough to perform well.

You can kind of tell when things just work well. As you probably know, I just run them down. But if I were at a big race, I would just run the first set down until I found around what height I was fastest- then true the rest of my foams to be 1-2 mm higher depending on wear.

I totally agree with you Lazy,
With a new set, I would purposely run hard during the warm up to get the rears down a little -- thats wehn my car performs well.
But during that time, I don't have time to have the tires measured for the different split in size -- too caught up in the race!
I just wondered if others would have a predetermined measurement for diameter split/difference, or size that would be corrected by ride height. Ride height played a big role in performace for me during the champs. As the tire diameters got smaller, I adjusted for ride height/droop/camber. Adjusting for ride height changed roll center for me, more so in the rear -- roll center was raised so the rear end didn't roll as much, allowing my car to rotate better from the rear.

I wish I had the time to really test and log things down...my log book is full from off-road stuff, and I'm pretty much trying to rely on my memory of settings that worked for me -- too bad it gets all blurry....then earased...after some beers

I've read somwhere that 63-62mm is about that optimum size.
